Delco Reassessment Project

In March 2017, Delaware County was court ordered to conduct a county-wide property reassessment.  In December 2017, the reassessment project began with data gathering; to be followed by verification of the accuracy of the data.  That will be followed by an appeals process in 2020, when the new assessments are scheduled to go out.  The reassessment will be reflected in 2021 tax bills.

Delaware County Council Warns Residents of Potential ScamDelaware-County-Reassessment-Project-graphic-300x240

Delaware County has been made aware of a resident reporting that a person posing as a data collector for the County’s Tax Reassessment Project requested to enter her home. The County reminds residents that the data collectors hired by Delaware County will never ask to enter a home. They have been trained to knock, identify themselves if someone is home, and inform the occupant of the reason for their visit. Data collection is done from the outside. The County also reminds residents that data collectors will always be wearing a bright yellow vest bearing the Tyler name on the back and displaying a county issued identification. If a resident encounters a person posing as a data collector and asking to go into their home they should immediately report it to police.

Residents can also call the Reassessment Hotline if they have any questions or concerns: 610-891-5695. Click Here to read Delaware County Council's press release of 08/23/2018.
